ADVANCED ALD1712A/ALD1712B LINEAR ALD1712 DEVICES, INC. RAIL-TO-RAIL PRECISION OPERATIONAL AMPLIFIER FEATURES GENERAL DESCRIPTION Linear mode operation with input voltages The ALD1712A/ALD1712B/ALD1712 is a monolithic precision opera- tional amplifier intended primarily for a wide range of analog applications 300mV beyond supply rails in +5V single power supply and 5V dual power supply systems as well Symmetrical complementary output drive Output voltages to within 2mV of power as +5V to +10V battery operated systems. All device characteristics are supply rails specified for +5V single supply or 2.5V dual supply systems. It is High load capacitance capability -- manufactured with Advanced Linear Devices enhanced ACMOS silicon 4000pF typical gate CMOS process and is available as a standard cell in ALD s ASIC No frequency compensation required --Function-Specifi library. unity gain stable The ALD1712A/ALD1712B/ALD1712 has an input stage that operates to Extremely low input bias currents -- +300mV above and -300mV below the supply voltages with no adverse 0.01pA typical Dual power supply 2.5V to 5.0V effects and/or phase reversals. It has been developed specifically with Single power supply +5V to +10V the 5V single supply or 2.5V dual supply user in mind. High voltage gain typically 85V/mV 2.5V and 250V/mV 5.0V Several important characteristics of the device make many applications Drive as low as 1K load with 5mA easy to implement for these supply voltages. First, the operational drive current amplifier can operate with rail-to-rail input and output voltages. This feature allows numerous analog serial stages to be implemented without Output short circuit protected losing operating voltage margin. Second, the device was designed to Unity gain bandwidth of 1.5MHz Slew rate of 2.1V/s accommodate mixed applications where digital and analog circuits may work off the same 5V power supply. Third, the output stage can drive up Suitable for rugged, temperature-extreme to 400pF capacitive, and 1K resistive loads in non-inverting unity gain environments connection, and up to 4000pF at a gain of 5. These features, coupled with extremely low input currents, high voltage gain, useful bandwidth of APPLICATIONS 1.5MHz, slew rate of 2.1V/s, low power dissipation, low offset voltage Voltage amplifier and temperature drift, make the ALD1712A/ALD1712B/ALD1712 a truly Voltage follower/buffer versatile, user friendly, operational amplifier. Charge integrator Photodiode amplifier On-chip offset voltage trimming allows the device to be used without Data acquisition systems nulling in most applications. The device offers typical offset drift of less High performance portable instruments than 5V/C which eliminates many trim or temperature compensation Signal conditioning circuits circuits. For precision applications, the ALD1712A/ALD1712B/ALD1712 Sensor and transducer amplifiers is designed to settle to 0.01% in 8s. The unique characteristics at input Low leakage amplifiers and output are modeled in an available macromodel. Additionally, robust Active filters design and rigorous screening make this device especially suitable for Sample/Hold amplifier operation in temperature-extreme environments and rugged conditions.
